19^2 + x^2 = 21^2
19^2 = 361
21^2= 441
361 + x^2 = 441
x^2 = 441-361 = 80
x = sqrt(80) = 8.944 round to nearest tenth = 8.9
I’m not too sure of what the equation is but I made a guess let me know if this was the right equation please I can redo it.
But, when solving this equation you are trying to find the value of x. To do that you have to get rid of the 3.
You would either add or subtract the 3 on both sides.
When the three is gone you should have somthing like
x = 5
- 3
Which you would move on to subtract the 5-3 and get 2.
x= 2
Here’s a picture of how I solved it
Answer:
i think i used it before
Step-by-step explanation:
X=side length of a campsite
12x(5+x)=1248 because each campsite has a length of x and there are 12 and from the top of the camp to the water is the 5 yds + a side length and LW=1248
60x+12x^2=1248
12x^2+60x-1248=0
x^2+5-14=0
(x+7)(x-2)=0
x+7=0 or x-2=0
x=-7 or x=2
x=2 because width can't be negative
the width of one campsite is 2 yds
The answer is a! i hope this helps you!
